Air Curtains

Commonly found in shop or retail outlet doorways, an air curtain is an electronic installation that creates a wall of air, powered by a fan. The air is either heated or cooled depending on the desired temperature, but the effect is felt instantly as customers and employees pass through the air curtain door. The air curtain heater or cooler does a lot more than just maintain temperature. It can also keep out dust, pollutants and other pests and insects which are repelled by the curtain.
